Mechanical Installation
The installation should be planned by a qualified structural engineer.
Each installation is unique, and this booklet is meant to serve only as an
overview for installation of the RL1800 Series Weigh Modules.
2.1
Installation Guidelines for Weigh Modules
In circular mounting configurations, the preferred mounting orientation is with the long axis
of the load cell pointing toward the center of the vessel.
Figure 2-1. Circular Mounting
For rectangular vessels, the long axis of the load cell should be parallel to the long
dimension of the vessel.
Figure 2-2. Rectangular Mounting
In any application where a recurring force is present in one direction, such as in a
conveyor belt or roller platform, the long axis of the load cell should align with that force.
Mounting surface for base plate and top plate must be level within ± 0.5
to minimize side
loads and extraneous forces.
• If the mounting surfaces are not level, shims or grout may be used to level the
module.
• If possible, check level and plumb again when container is fully loaded; the
deflections in legs and supporting structures may cause additional side forces
which greatly affect accuracy.
• Reinforcement, such as cross bracing of legs or other support structures, may be
needed to correct this.
• Deflections of modules top or base plate due to loading should not exceed ± 0.5
